HENRY C. SCHANZE, $3., OF CAMDEN, NEW JERSEY.

DEVICE FOR AERIAL NAVIGATION.

Specification of Letters Patent. Application filed November 25, 1908.Serial No. 464,345.

Patented May 3,1910.

To all whom it may concern:

Be it known that I, HENRY C. SCHANZE, Sn, a citizen of the UnitedStates, residing at Camden, in the county of Camden and State of NewJersey, have invented certain new and useful Improvements in Devices forAerial Navigation; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it a pertains to make and use thesame.

hf; invention relates to new and useful improvements in devices foraerial navigation, particularly of the propeller type.

As indicated, it has for its object to rovide means for makingpractical, aeria or overhead navigation, Wlllch shall be highly buoyantand under'ready and effective control of the operator and capable ofguarding ment Sald invention also has for its object to carry out theaforesaid ends in a simple,

Other objects and advantages will be hereinafter referred to and moreparticularly pointed out in the claims.

In the accompanying drawings which are made a part of this application,Figure 1 is a longitudinal section of the -invention with parts thereofin side elevation. Fig. 2 is a plan view of the same. Fig. 3 is avertical transverse section thereof, with arts in side view. Fig. 4 is abroken or fract1onal sectional view upon an enlarged scale disclosingmore especially frictional bearings for the propeller shafts, and, Fig.5 is a detached perspective view of one of the propellers.

In describing the invention in detail, reference will be had to theaccompanying drawings forming .part of this specification, wherein likecharacters of reference denote corresponding parts in the several views.

In carrying out my invention, I provide a car or housin 1, preferablyhaving its frame work forme from alloyed aluminum and the shell thereofformed of aluminum, said frame work and shell being preferably of 1;}inches and inch in thickness, respectively. Said car or inclosure 1 isprovided with observation windows 2 in its up er portion, fore and aft,filled in preferab y with extra heavy glass, and formed in the lower\ortion of said car near the bottom, are adgitional preferablyslide-covered openin 3, one at each end, or fore and aft and t e 1 thirdabout centrally thereof in both sides of the car, the slides thereofbeing formed with air-t1 ht compression joints. The under side 0 saidcar or inclosure is formed into a downwardly opening compartment 4,designed to form an air cushion to aid in controlling the descent of thecar by the action of the air cushion formed in the com,- partment 4.

A number of vertical shafts 5 are arranged at suitable intervals apartwithin the car or housing 1 and extend tendin portions being .equipeller hlades 6, the lower en s of theshafts 5 being suitablyintergeared as at 7 and 8, with a horizontal shaft 9, suitably journaledin said housin' or car near its floor, said horizontal shai t beingdriven or receivin its motion from suitable motors 10 arrange in thebottom of said housing or car and which are of suitable horse power, thepreferred ty e, being the La Antoinette not shown. i lso arranged insaid housing or car 1 upon the floor thereof are suitable fuel oroil-holding tanks 10 for replenishing the motors with fuel whennecessary.

The pro ellers' 6 are each formed preferably of three blades 11preferably of reinforced aluminum or wood set at the reguisite angles inaluminum frames 12 ra iating from a central tubular member 13 also ofaluminum, the same being braced and strengthened a ainst possibility ofaccidental breakage. %he propellers 6 of each shaft are arranged in agraduated series of three, the top one being the smallest, the purposeof Which is thought to be obvious, said propellers having their. angularpositions'of such arrangement as to cooperate in utilizing the mutualaction of said propellers u on the air. An additional or supplementalike arrangement of shafts and propellers 14 and 15, but of less liftingand driving capacity, is arranged about centrally of the housing or carand laterally of the central or main shaft and propellers with theirshafts geared as at 16 to a horizontal shaft 17, each suitablycontrolled froma supplemental motor 1 and which ad d1- tional propellersmay be brought into action in event of the failure of the mainpropellers or any one of them to operate.

The propeller shafts 5, as also the shafts ped with proof thesupplemental propellers, have their rovided with balls 18 interposedbearin gs caring plates 19, said bearing between thereabove, such ex- 7plates having said shafts passing therethrough, as shown in Fig. 4, thelower one of the upper pair of plates being bolted or otherwise securedto said shafts, as at 19, the plates or members 20 of said bearingsbeing arranged in pairs above and below the cor of the car 1 and saidshafts 5 being held to said pairs of bearing plates by nuts 21 and 22screwed upon said shafts, said nuts being held in eflective position byjam nuts 23 and 24. Of course, it will be under stood that thisarrangement of bearing plates and balls may be substituted by any othersuitable form of bearing without affecting the spirit of my inventionand therefore be within the range thereof. It will be understood thatthe bearings may be filled in with brass and Babbitt metal, as is commonfor this purpose.

Arranged at the forward-end of the housing is a propeller 25 and attherear end'of the car or housing 1 is also arranged a like propeller 26forming in connection with other parts presently disclosed what may betermed gyroscopes, both of which propellers areadapted, by means laterdescribed, to be adjusted or an upward angular position and the other tobe moved in a downward angular position for varying and controlling theangle of the movement of the machine in either an upward or downwarddirection, as will be readily appreciated. Said propellers 25 and 26 arecarried by shafts 27 and 28, having their journals or bearings 29 and 30received by the uadrants 31 and 32, respectively, suitably .xed to saidhousing and projecting downwardly and upwardly therefrom, re spectively,said quadrants providing for guiding and controlling the angularmovement imparted to said shafts and said. propellers 25 and 26. Saidhousing is provided at its forward and rear ends, in its upper and lowersurfaces, with slots or openlugs 33 and 34, respectively, to permit ofthe aforesaid movement of the shafts 27- and 28, as is apparent. Saidpropellers of the gyroscopes as thus constructed may have a drivingspeed upwardly of one hundred and fifty to three hundred revolutions perminute and may have a lifting speed. from one hundred to three hundredrevolutlons per minute. i

The motor casings, which are hung or pivoted in suitable supports 38arranged in the housing or car, have connected thereto pendent arms 39,which are connected together by means of a common rod 40 adapted to beactuated by a manually actuated lever 41 suitably equipped with ahousing de'tent 42 engaging a rack 43 secured to the floorof the housingor car. It will, there- 'fore, be noted that by suitably actuating themoved, the forward one lIl.

lever 41, the shafts 27 and" 28, together with the pro ellers 25 and 26may be simultaneously a justed or moved into the positions aboveascribed to the latter and thus held, as may be desired.

The car or housing 1 is also rovided at its rear end with a rudder44aving piv-- ot-al or hinge connection, so as to swing hor1- 4 zontally,to a frame or skeleton member 45 to provide for suitably steering thedevice in. its flight or movement through the air, said rudder havingconnected thereto a, transverse rod 46, passing about centrallytherethrough, said rod having connecte thereto at its ends, lines orcables 47 carried forward and suitably coiled or wound around a pilotwheel 48 suitably arranged at theforward end of the machine and underthe control of the operator. It is also noted that the gearing hereindescribed may be made of solld alloyed aluminum, as also the ballbearings above described.
